Application filed June 4, 1912. 'SeriaI No. 701,519.

To all whom it may concern.

Be it known that I, DUDLEY S. SEYMOUR, a citizen of the United States, residing at Oak Park, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Filled-Bag-Sewing Machines, of which the following is a description, reference being bad to the accompanying drawing and to the figures of reference marked thereon.

My invention relates to new and useful improvements in machines for sewing filled sacks, and more especially to devices of this character in which the sack is brought by a conveyer to the stitching mechanism and fed past such stitching mechanism. It is desirable in this class of apparatus that the conveyer be driven independently of the sewing mechanism, the former carrying the sack to a point adjacent the stitching mechanism before the latter is set in operation.

It is desirable also in machines of this character, that the operator should have both hands free to properly place the sack with its mouth so as to be fed to the stitching mechanisnnand also that the conveyer and stitching mechanisms should be under ready and simple control by the foot of the operator, and to lessen his work, that the conveyer and stitching mechanism should be successively set into operation by substantially one movement on his part.

An object, therefore, of the present invention is to provide means for controlling successively by a single lever, the clutches which operate the vertical operating conveyer shaft, and the vertical operating stitching mechanism shaft, on an organized filled bag apparatus.

A further object is to provide two independent driving connections for the sewlng mechanism and conveyer respectively, which driving connections include separate clutches, and a common controlling mechanism for the two clutches, so. constructed that one may operate in advance of the other.

These and other objects will in part be obvious and will in part be hereinafter more fully described.

The invention is illustrated in the accompanying drawings, in which, I

Figure 1 is a front elevation of a filled bag sewing apparatus showing my invention applied thereto;

Fig. 2 is an enlarged sectional view, showing the dual drive mechanism.

Referring to the assembled machine as shown in Fig. 1, it is of the Union Special type of filled bag sewing apparatus, as

shown in general in.Patents Nos. 875,314,

187 5,339, of December 31st, 1907, and shown more-specifically as to the adjustable head type in various pending applications filed by me, of which application Serial No. 5 536,765, filed January 6th, 1910, is an example. The framework 1, the endless conveyer 2, the sprocket wheel 3, driving the latter, the sewing head-supporting bracket 1, the bracket 5 supportlng. the conveyer, and the -means for raising and lowering the conveyer operated by the crank handle 6, are all of a usual and well known construction. The source of power for operating the mechanism is herein shown as an electric motor 7, from which power is transmitted to a fiatpulley 8, loosely mounted on the upright shaft 9, which is suitably connected to 'the cross shaft which carries the sprocket 3 for operating the conveyer belt. The pulley 8 has an elongated hub 10, and is supported on a ball bearing 11, and, as above stated, is

loose on the vertical shaft 9. I call this the the first movement thereof clutches the pul- 1ey 8 to the member or pulley clutch 14, and

the vertical shaft 9'is, therefore, rotated,

thus transmitting movement to the conveyer 2.. w

Carried by a hub or sleeve 15' journaled in a bearing bracket 16,,is a friction clutch 'member 17. Its hub 15 is fixed to the shaft 9, and has a ball bearing support 18 on the bracket -16.

' Above the shaft 9, is a second upright shaft 19 carrying the belt wheel 20, which is connected by a belt 20 to the driving 60 her,

19. It will be understood that splines are placed on the shafts whereby the operating devicemay be moved up and down the sew- 1 ing head, and conveyer adjusted, as shown in my aforesaid application, No. 536,765.

This engagement of members 17 and 21 takes place when the operator passes the treadle sufficiently to raise the member 14- 15 and with it the shaft a sufficient height.

. It will be seen, therefore, by this construction that when the operator depresses the treadle, he will first cause the frictional engagement of pulley 8 and conveyer clutch friction 14, thus driving shaft 9, and operating the conveyer to carry the sacksthereon toward the sewing mechanism.

When the sewing mechanism is; reached by the bag in its movement, increased pressure on the treadle will cause engagement of members 17 and 21 of the upper clutch mechanism, and thus rotate the upper shaft andndrive the sewing mechanisirmthrough the belt wheel 20. The movable clutch mem- 3 bers return to normal position by gravity.

The swinging lever 13 carries, 'a suitable brakeshoe, as shown in Fig. 2, which moves into engagement with the friction clutch member 14 when theclutch parts are separated.

' While I have shown and described my invention, and primarily have designed it for use in connection with the successive bringing into operation of the conveyer and 40 thesewing mechanism of a filled bag sewing apparatus, it will be understood that so far as the mechanical movements set forth are applicable to other uses, the invention is not limited to this particular type of apparatus.
